Introducing our new generation TERA K15 Systems with unparalleled performance
The TERA K15 fiber-coupled terahertz spectrometer offers a comprehensive solution for high-speed
broadband time-domain THz spectroscopy, delivering exceptional flexibility for scientific applications.
By incorporating our groundbreaking TERA15 antenna modules, the new generation TERA K15 system exhibits unprecedented enhancement in performance. The TERA K15 integrates every featureof the TeraSmart and adds further versatility options, earning it the “multi-talent” reputation amongstour product line.
The dual-detector option can be used to enable measurements in both transmission and reflection
geometries on a given sample. For THz imaging applications, our TERA Image extension, completewith advanced software for imaging acquisition and reconstruction, can easily be integrated into yoursetup to unlock and facilitate your experiments. To fully leverage the modularity provided by the TERA
K15 platform, you can opt to synchronize the system to an external laser and/or extend it with supplementary laser output ports at 780 nm, 1040 nm and 1560 nm wavelengths. Given these features,
the TERA K15 provides a unique interface for optical pumping – terahertz probing and can serve as
an ideal testbed for exploring innovations in photonics and semiconductor science.
The TERA K15 integrates Menlo Systems’ cutting-edge fiber-based femtosecond laser operating at
an emission wavelength of 1.5 μm, utilizing our proprietary figure 9® mode-locking technology. Additional components include a fiber-coupled optical light path with a fast delay line, customizable THz
free-space optics, including THz emitter and detector. The system is equipped with control electronics
and a PC fitted with data acquisition and evaluation software. The delay line offers a flexible scan
range that covers a standard scanning window of >850 ps with a spectral (THz) resolution below 1.2
GHz. For customers seeking the highest spectral resolution (<0.6 GHz), an extended scanning range(>1700 ps) is available as an option.
